Banfield moved off the bottom of the Apertura with a 3-0 win over Independiente.
Ricardo La Volpe's men scored all their goals in the second half at Estadio Florencia Sola, with Facundo Ferreira's brace supported by a last-minute effort from Walter Acevedo.
That did not tell the full story, though, as Independiente had to play an hour with 10 men following Julian Velazquez`s first-half dismissal for handball.
Elsewhere, Juan Avendano`s 60th-minute goal moved Union Santa Fe into the top eight as they beat Olimpo 1-0, while All Boys drew 1-1 at home to Newell's Old Boys.
All Boys had Hugo Barrientos sent off for two yellow cards inside a minute, but still took a 33rd-minute lead through Juan Rodriquez.
But Fabian Munoz levelled in first-half injury time to earn Old Boys a point.
